Extremely terrible service

I've been trying to update my credit profile with CompuScan (Experian) since last year December (10/12/2020) to date and they still refuse to help me. I've disputed my profile a number of times, and every single time I'm always asked to fill in a form. Yet nothing gets done about this. I just disputed the wrong listing again and I'm still requested to fill in the form. Why is CompuScan refusing to update my profile and why do they always tell me it will be updated once the creditor has sent through the information, even though I have proof that the account is closed?

The service from this company is pathetic and I know for a fact they don't care, otherwise I wouldn't be complaining here after 7 months.
